If number of electrons in an atom is 8

Asked by admin @ 12/08/2021 in Chemistry viewed by 294 People

If number of electrons in an atom is 8 and number of protons is also 8 then (neutrons=7)

1.what is the atomic number of the atom? 2.what is the charge in the atom? 3.what is the mass number of the atom?

Answered by admin @ 12/08/2021

Hey there !

Solution:

Number of Protons = 8
Number of Electrons = 8
Number of neutrons = 7

Atomic Number = Number of electrons = Number of protons

=> Atomic Number = 8

Charge of an atom = Number of protons - Number of electrons

=> Charge of an atom = 8 - 8 = 0 ( Neutral charge )

Mass Number of an atom = Number of Protons + Number of Neutrons

=> Mass number = 8 + 7 = 15 u

Hope my answer helped !
